SPECIFICATION forming part of Letters Patent No. 601,387, dated March 29, 1898.

Application fil d April 14, 1896. Serial No. 587,500. (No model.)

To all whom it may concern:

Be it known that I, NELSON J. TUBBs, a citizen of the United States,residing at Knoxville, in the county of Knox and State of Tennessee, have invented certain new and useful Improvements in Churns; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

This invention has for its object the provision of an improved mechanism whereby in butter-making the butter globules are thoroughly separated from the other constituents of milk or cream without disintegrating the butter globules or uniting with them casein, milk, or other refuse substances, and this at a saving of time, labor, and material.

The device consists of the following instrumentalities: First, a rotary dasher of wood or metal, upon the face of which are angular projections or hips, the apices of which converge to the center of the .dasher, which is pivoted in the bottom ofvthe churn or butter-. separator; second, a tubular connectingshaft engaging with said rotary dasher, slots or perforations in'said tubular shaft, an airdrum attached to said shaft and surrounding said slots or perforations, hooded apertures in the top of said air-drum, and aeratingtubes leading from the interior of said tubular shaft, and near its base, to, or near to, the

rim of thedasher, the tubular shaft being connected by an adjustable sleeve with a pulley-shaft journaled in the pulley-arm of an upright frame; third, an auxiliary dasher or agitator composed of obliquely-set paddles, of wood or metal, united by a ring inclosing said tubular shaft, adjustable, by means of a set-screw, to any desired height; fourth, slotted wings, removable at will, provided with brads on the bottom and outer edges and braced by a connecting spring engaging notches on the inner sides of said wings, which are attached to the sides of the churn or butter-separator preferably in an oblique power transmitted by a pulley or a series of pulleys from a band or power wheel operated by hand or otherwise, whereby a centrifugal wave or wall is created, which is broken and diverted in a centripetal direction by the slotted wings only to be again repelled by the centrifugal action of the rotating dasher into the undercurrent and overcurrent which has passed unobstructed throughthe slots in said wings, so that a more complete agitation of the contents of the churn or separator results,

while the rotation of the air-drum causes a thorough aeration of the milk or cream, the air being better collected by the drum and better distributed into the fluid through the aerating-tubes than in any other device of a similar character.

In the accompanying drawings, forming a part of this specification, Figure 1 represents a side elevation of the device embodying my invention, the sides of the churn or butterseparator being broken away the better to exhibit the construction and mode of operation of my improved mechanism. Fig. 2 represents the aerating device, a material feature of my invention, the sides of the airdrum being broken awayto show the aerating slots or perforations in the tubular connecting-shaft. Fig. 3 represents a top view of the rotary dasher. Fig. 4: represents a transverse section of said dasher. Fig. 5 represents a top view of agitator or auxiliary dasher. Fig. 6 represents a front view of the slotted wings.

In the drawings similar letters refer to similar parts of the device.

7 In the drawings, F is a post or beamadj ustedto the base f and provided with the pulley-arm E- S is a pulley-shaft journaled to said pulley-arm at .9, provided with horizontally-rotating pulley e and with the adj ustable sleeve s which is provided, preferably, with the set-screw 8 The pulley-arm E is also provided with the pulleys e and a operating at right angles to each other and with the set-screw 6 P is a band or power wheel (preferably of the bicycle type when hand-power is used) provided with the axle p, in the form of a screw-bolt, engaging, through the sleeve 1),

with the post or beam F. The band or power wheel P is also provided with the band or belt B, which is geared to the pulleys e 6, and a sleeve s which is'provided with the setscrew so'that the revolution of the band or power wheel P rotates the pulley-shafts.

The tubular connecting shaft T is closed at the top and at its base and is connected with.

the'pulley-shaft S by means of the adj ustable 1. The tubular connecting-shaft T is provided in its upperthird with the slots or per- 7 V forations' about which'is fitted the air-drum tures t gaud withtheaerating-tnbes t.

'G'is a churn or buttei separator provided with a suitable cover, fitting about the tubujournal or socket of the usual form. r

The operation of the device is as follows;

The mechanism being assembled and in the 7 position shown in Fig. '1, the churn or separator containing milk or cream, therevolution tary movement to the pulleyshaft S by means :of the band B operating on the pulleys 6 e,

. and 6 thereby rotating the tubular shaft T, the air-dr m t, theaerating-tnbes t, the dasher I D, and the agitator 'orauxiliary dasher A on the pivot d. The centrifugal wave or wall created by the rotation of the dasher D and the agitator or auxiliary dasher A being broken and diverted in part in a centripetal manner by the wings W, theunder and over currents created by the portions of the wave or wall which pass through the slots 10 being broken or chopped by. the diverted portion of said wave or wall, which, after having been thrown toward the center by the wings W, is strongly repelled by the centrifugal action before referred to into the currents that have passed uninterruptedly through the slots w, whereby a complete agitation of the fluids results, While the air fanned down the tubular I shaft T by the air-drum 25 through the slots or perforations If is discharged, not in the trough created by the centrifugal action of the dasher D, as in other devices having a similar purpose, but directly into and under the centrifugal wave or wall before referred to by means of the aerating tubes 25, so that all the air fanned down the tubular connecting-shaft T is forced violently into said centrifugal wave or wall, whereby a complete aeration of the fluid ensues, the aircurrent before referred to also cooperating to secure a complete agitation of the milk or cream, because expelled into it with a connected and removed, as isapparent. agitator or auxiliary dasher A and the 'pul- To the force proportionate tothe rapidity of the revolutions of the connecting-shaft T, as is apparent; It will be further observed that thetubularconnecting-shaft T is adj ustable V to churns or separators of different heights by means of'the connectingrsleeve: s and'the I The ley arm E, being providedwith the set-screws 1 r V lar connecting-shaft T and the post or beam F, respectively, the'band or power wheel P being provided with the sleeve 1) and the a" and eflare adjustable toany height onor' susceptible of being removed from the tubu: 1 I 7 8o 1 axle p, thelatter in the form ofa screw-bolt, V
